The first collections, from 1834, belonging to St. Sabba Academy, lay the foundation of the museum, that currently holds items illustrating the domains: ecology, zoology, oceanography, paleontology, taxonomy, and morphology. The zoological collections of the museum - the most numerous and diverse in Romania - make possible a thorough documentation of biodiversity on the territory of this country and even beyond its borders; the geological and paleontological collections reveal the peculiarities of the evolution of the earth and of the fauna on the present Romanian territory; and the ethnographic collections emphasize one of the subtlest aspects of biodiversity: socio-cultural diversity. The ...museum is one of the best known institution with complex zoological research, involved in collaborations with other museums, institutions and universities in America, Australia and Asia. Trips to Tanzania (1973), Indonesia (1991) and Brasil (1994) were organised. The museum library comprises over 30,200 books, and 20,000 periodicals. The museum owns property listed in the National Cultural Heritage Treasure.
